5 Claims.

This invention relates to hinge construction and particularly to a hingefor an oven door.

Small portable cook stoves of the type that may be conveniently placedon the table or shelf and are just large enough to receive onereceptacle for toasting, baking, frying or the like are finding publicfavor. manufacture such stoves at as low cost as possible, it isnecessary that the oven or cooking compartment thereof be provided withan accurately fitting closure in order to prevent unnecessary escape ofheat and thus increase the efliciency of the cooking operation.

Die stamping is preferable in the manufacture of the walls and variousparts of such stoves but it is found that the formation of an accuratelyoperating hinge on an oven door cannot be formed practically and cheaplyby die stamping operations.

It is therefore, the object of the present invention to form an ovendoor and hinge therefor that will provide a close fitting closure forthe cooking compartment of a small stove and in which the metal partsof-the door and door frame may be made by simple die stampingoperations.

One form of my invention is exemplified in the accompanying drawing anddescribed in detail in the following specification.

In the drawing:

Fig. 1 is a perspective view of a front wall of an oven fitted with anoven door hinged thereto in accordance with my invention.

Fig. 2 is a fragmentary perspective view showing the construction of theoven door.

Fig. 3 is a similar view showing the'construction of the door frame.

Fig. 4 is a sectional view taken on the line IV-IV of'Fig. 1 with theoven door shown in an opening position.

Fig. 5 is a section taken on the line VV of Fi 1. 7

Referring more particularly to the drawing, the front wall of an oven isshown at I 0. This oven wall is preferably made of sheet metal andformed by die stamping. A door opening is formed centrally of the wallI0 and surrounded by a channel shaped frame II pressed from the materialof which the wall is made. A door I2 is provided for closing the openingsurrounded by the frame I I and is formed with a central depression anda marginal flange I3 so that it fits snugly against the outer surface ofthe frame. The lower edge of the door is formed with spaced tangs whichare curled to form bearings I 4 for the reception of a pintle pin I1,and the lower edge of the channel shaped frame II is provided While itis desirable to' prising bearing members formed on the door for withelongated openings I5 through which the bearings I4 may be inserted. Anopening I6 is provided at one end of the frame II, as shown in Fig. 1,so that when the bearings I4 have been inserted through the openings I5,the pintle pin, 5 which is long enough to extend through all three ofthe bearings I4, may be passed through them and disposed within thechannel shaped frame in the position shown in Figs. 4 and 5.

When assembled as above described, the pintle 10 pin I1 serves to retainthe door against separation from the frame and also cooperates with thebearings I4 and frame to form a loosely connected; hinge. This hingebeing loosely connected permits the door to close against the frame with15 the abutting surfaces tightly fitted. It does not, however, maintaina tight fit when the door is being opened and closed.

In order to provide an accurately fitting bearing that will maintain thedoor in proper align- 20 ment with the opening as it is opened andclosed, the interior of the channel shaped frame II along thesidethereof that is occupied by the pintle pin is filled with a plastic heatresisting composition designated by the numeral I8 in Figs. 4 25 and 5.This composition is preferably asbestos cement or may be a plaster ofParis composition, or any other suitable material that may be forcedinto the frame in aplastic state and is capable of setting to provide ahard heat resisting material.

- The composition I8 is forced into the frame when the door is in itsclosed position and. therefore surrounds the exposed parts of the pintleI! when it is in a proper position to form an accurate hinge between thedoor and the frame. 35 Upon setting, the composition hardens about thepintle pin and therefore forms bearings so that the door may be openedand closed freelyand will always upon being closed form a tight seal,preventing unnecessary escape of heat from the 40 oven chamber.

From the foregoing it will apear that I have provided a novel hingeconstruction which is simple and inexpensive to manufacture but capableof maintaining a door in accurate alignment with the opening that it isintended to close.

While I have shown my invention in its preferred form, it will beunderstood that various changes may be resorted to in the constructionand arrangement of its several parts without varying from the scope ofthe appended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

l. A hinge for fastening a door to a frame comthe reception of a pintlepin. and a plastic ma- 5 terial carried by the frame and forming ahearing for the pintle pin.

2. A hinge for fastening a door to a frame comprising bearing memberscarried by the door for the reception of a pintle pin, said frame havingopenings through which said bearing members extend, and a plasticcomposition behind the frame in which the pintle pin is embedded.

3. A hinge for fastening a door to a frame comprising bearing memberscarried by the door, a pintle pin carried by said bearing members, and abearing member in the frame consisting of a plastic compositionsurrounding the pintle pin.

4. A hinge for fastening a door to a frame c0mprising bearing membersfor a pintle pin on said door, a channel shaped edge on said framehaving holes through which said bearing members extend, and a plasticmaterial contained by said channel shaped edge and embedding said pintlepin to form bearings for the pintle pin.

5. A hinge for fastening a door to a frame which comprises a pintle pinsupported by the door and lying within the frame, and a plastic compoundsupported by the frame and forming 10 a bearing and the sole support forsaid pintle pin with relation to the frame.
